Re: PR14962 fix

[Alan Modra <amodra at gmail dot com>]

This is the testcase I was using.  Since it isn't ELF specific, and it
shows up other real bugs, I'm committing this even though HJ already
committed a testcase for the PR.

	PR ld/14962
	* ld-scripts/pr14962.d, * ld-scripts/pr14962.t,
	* ld-scripts/pr14962a.s, * ld-scripts/pr14962b.s: New test.
	* ld-scripts/expr.exp: Run it.
